Hey guys I May have missed something but when does the MC get a motivation to corrupt the girls with his cum (or realizes he can do so and decides to try it)? Because when he first leaves Gwen's hut he's denying his gift and seeing it as a curse. Even when you come back to her to ask for a way to get rid of it he haves sex with her to satisfy his unbearable urges.
You choose whether it is a curse or blessing.
You can choose to suppress the corruption, or can corrupt girls willy nilly.
The motivation is that corrupting girls gives you way more sex scenes, makes the girl more agreeable to sharing you with other women, and for some specific women lets you get around their reluctance to be with you in the first place.
You also later are given an offer by gwen. which, if you viewed it as a curse you wouldn't accept.
Game doesn't force you to hold an opinion here, it lets you choose.
